If you use Chrome on your iPhone or iPad, and you’re not running the latest version, you may want to update it. Google has started inviting selected users to enable the data-compression feature it first launched on Android back in March.

For an average web page, over 60% of the transferred bytes are images. The proxy optimizes and transcodes all images to the WebP format, which requires fewer bytes than other popular formats, such as JPEG and PNG. The proxy also performs intelligent compression and minification of HTML, JavaScript and CSS resources, which removes unnecessary whitespace, comments, and other metadata which are not essential to render the page. These optimizations, combined with mandatory gzip compression for all resources, can result in substantial bandwidth savings.

Or, in less technical terms, Chrome strips out everything not needed to display webpages properly, so you get the same experience but with up to 50% less data usage. For those who do a lot of browsing on 3G/4G, that can make a big difference to your monthly data bill.

So far, only a relatively small number of users appear to have been invited to participate, but that number is likely to grow over the next few weeks.

According to Rapidus.se (via TechCrunch), Apple has purchased a Swedish firm called AlgoTrim for an undisclosed price. The small company specializes in image and video, specifically JPEG, compression techniques on mobile devices which allow faster processing of images on power-constrained mobile devices.

AlgoTrim™ develops advanced solutions for mobile devices within the fields of data compression, mobile imaging and video, and computer graphics.

These solutions are designed to excel in terms of high performance and small memory requirements, making them ideal for mobile devices. Many solutions offered by AlgoTrim are codecs that are the fastest on the market, for example, the lossless codec for general data compression and the imaging codecs.

Apple could use these codecs in its camera and image viewing and manipulation apps on iOS. It is probable that the cost of picking up the company and owning the technology outweighed the cost of licensing the technology over its hundreds of millions of devices. This also could be an “aquihire”.
